I am inquiring if anyone else has had trouble with Retumbo?? I am or was trying to develop a load for my 6.5WSM with it and am getting extreme high/low deviations. I am trying as hard as I can to keep things uniform, but something is wrong. I've had loads that ranged from a very useable 3155 to a primer blowing 3243 fps. That's quite a bit isn't it??? I called Hodgdon a while back as I was having trouble finding the powder. They said they had recalled over 4,000 pounds of it, so the market was pretty dry. Sound like a possible bad lot or just my equipment??

Seems to me that re 25 was a little inconsistant for a while to. At first people showed loads near h1000 and now it seems to act just a tad bit slower than 7828. Evidently it may be like when a new car or truck comes out--you might want to wait a year or so before the bugs are worked out.

Russell,

If you don't mind me asking. What loads are you using in your 338/378. I have one that I haven't started reloading as of yet.

I haven't used the Retumbo yet (I have tons of other "gun projects" ahead of it), but my current load is 121 grains of H50BMG under a 300-grain Sierra Match King, kicked off with Fed 215M primers.

111 grains of H5010 (slightly compressed load; drop tube would help) with 250 gr. Sierra for 3050 fps to match factory load.

Correction: IMR 5010, NOT H5010!

I have shot Retumbo recently in working up loads for a buddies .338 Lapua and testing a 30-378 Wby, for another buddy. I have been impressed with it's consistency and accuracy. Looking forward to more use in the future. Good shooting.

I'm still upset that Hodgdon dropped the H870 from their line. It figures that it was the most accurate powder in a new wildcat that I am working on. I will try the Retumbo as soon as it is available around here but that's just a shot in the dark.

Jesse Jaymes,

I have used Retumbo in my 22/284,6.5WSM, 6.5STW, 300 RUM with excellent results. I got the 8lb keg about 3 Months ago and have had very good consistency in velocity(like H1000). It seemed to work better in my 6.5STW and 300 RUM for the loads I tried. Never saw velocity spreads like your talking about unless I was over pressure; not since I used H870. This recall makes me want to use this keg a little slower.
